■The meters and display illuminate when
The engine switch is in IGNITION ON mode.
■Instrument panel brightness adjustment
The instrument panel brightness levels when the tail lights are on and off can be adjusted
individually. However, when the surroundings are bright (daytime, etc.), turning on the tail
lights will not change the inst rument panel brightness. At th is time, any adjustments made
to the instrument panel brightness levels will be applied to both settings at once.
■Outside temperature display
In the following situations, the correct outside temperature may not be displayed, or the
display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 12 mph [20 km/h])
●When the outside temperature has changed suddenly (at the entrance/exit of a garage,
tunnel, etc.)
■Pop-up display
●In some situations, such as when a switch operation is performed, a pop-up display will
be temporarily displayed on the multi-information display or the odometer/trip meter
screen (F SPORT models).
●Some pop-up displays can be set on/off. ( →P. 92)
■Customization
The meter display can be customized on the multi-information display. (→P. 92)
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indicates
the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is in the red
zone (H). In this case, immediately stop the vehicle in a safe place, and check the
engine after it has cooled completely. ( →P. 566)

■Engine coolant reservoir
The coolant level is satisfactory if it is between the “FULL” and “LOW” lines on
the reservoir when the engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW” lin e, add coolant up to the “FULL” line.
( → P. 566)
■Intercooler coolant reservoir (IS200t)
The coolant level is satisfactory if it is between the “F” and “L” lines on the res-
ervoir when the engine is cold.

If the level is on or below the “L” line,
add coolant up to the “F” line.

■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid
organic acid technology.
U.S.A.:
“Toyota Super Long Life Coolant” is a mixt ure of 50% coolant and 50% deionized water.
(Minimum temperature: -31 °F [-35 °C])
Canada:
“Toyota Super Long Life Cool ant” is a mixture of 55% coolant and 45% deionized water.
(Minimum temperature: -44° F [-42°C])
For more details about engine coolant, contact your Lexus dealer.
■If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock and water
pump.
If you cannot find a leak, have your Lexus de aler test the cap and check for leaks in the
cooling system.
WARNING
■When the engine is hot
Do not remove the engine co olant reservoir cap, radiator cap (IS350/IS300) or inter-
cooler coolant reservoir cap (IS200t). ( →P. 569)
The cooling system may be under pressure and may spray hot coolant if the cap is
removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of water and
antifreeze must be used to provide proper lubrication, corrosion protection and cool-
ing. Be sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
